RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 694,058, dated February25, 1902. Application filed September 10,1901 Serial No. 74,982. (Nomodel.)

accompanying drawings, which form apartof this specification. a

The object of our invention is an itnrgovement on that class of devicesused on stfeetcar railways whereby the motorman or driver by moving alever can throw the switch, without stopping the car. This can be doneeasily by use of our invention, which will be fully explained in thefollowing specification, in

which the accompanying drawings are a part thereof.

Figure 1 shows a side elevation of a streetcar with our device attached.Fig. 2 is a plan view of a street-railway switch. Fig. 3 is across-sectional view of Fig. 2, taken on the line 3 3. Fig. at is afront view of the car, partly in section, showing our device. Fig. 5 isa top view of our invention as shown in Fig. i. Fig. 6 is a perspectiveview of the 0 shoe used in our device.

In the drawings, A represents the body of a street-car.

B represents the street-car rails.

B is a vertical shaft, having at the upper 5 end and suitably attachedthe handle I) and at the lower end the pulley-wheel b beneath thecar-bed.

is the chain used to raise and lower the shoes D to the track whennecessary. This chain passes around the pulley-wheel b and then throughthe pulley-wheels 19 The ends of this chain are secured to the hangers0, these latter being pivotally secured to the car-body at c. The shoesD are rigidly fixed to these 5 hangers G, and thus by means of the chainb they may be raised and lowered by the movement of the handle I) onshaft B.

B represents the switch. B is the swinging point of the switch, pivotedat b". The main object of our invention is to throw this point of theswitch, so as to change the direction of the car. To do this we employour newly-invented device, which we will now further explain. In this, Dis a lever placed vertically along eachside of the track near theswitch. It is pivotally connected at d to a fulcrum d and the latter issecured to the rail by nuts (1 This lever is also pivotally connected toa rod D at d. This rod is laid in a pipe D and extends from side toside, as shown in Fig. 3, or, in other words, extends from the lever Don one side to Doii 'theother, where it is secured in like manner. f

O is a vertical pipe made larger than the pipe D so asto allow a sidemovement of the rod, 0 which is rigidly'fixed to the switch-- point B ashort distance from the pointed end. This pipe 0 will have a slotted capfor this movement.

This entire switching device under the track should as far as possiblebe tightly boxed in, so as to avoid the clogging up by dirt, &c.

The shoe D will have an inclined face E, so as to create a wedge-shapedmeans of entering between the lever l) and the rail. To prevent thisshoe from going too far downward, we provide for it a sliding portion 6.This will rest on the surface or top of the rail and move along on thesame. The lever 17 will have the usual means of locking the same as innotches e.

In operation in coming to a switch the operator simply turns the leverso as to throw the proper shoe down on the track, where it entersbetween the lever D and the rail, thus opening and throwing outwardlysaid lever and by the fulcrum d throwing the lower part of the leverlaterally, thus moving the switchpoint, as has been mentioned.

The shoes D will be of a weight suflicient to drop firmly on the railand remain in position.

Having thus described and shown our invention, what we claim as new, anddesire to secure by Letters Patent of the United States,

1. The combination of track-rails and a pivoted switch-point,fulcrumsprojecting outwardly from the track-rails, levers pivoted intermediatetheir ends to the fulcrums with their upper ends adjacent to thetread-sur- ICO face of the rails, a rod D connected pivotally to thelower ends of the respective levers, a Vertically-extending rod Cconnected to the rod D and the switch-point, and devices on the car toraise and lower the said shoes from and to the rails, said shoes eachhaving a plate portion 6 to rest and slide upon the treadsurface of arail and a wedgeshaped portion E to slide between the outer face of therail and upper end of said levers, substantially as set forth.

In testimony whereof we have hereunto affixed our signatures in thepresence of the subscribing witnesses.
